Intaneti Multimeter Deuteronomo-830B: Buku wosuta, ndi ndemanga

Multimeter Deuteronomo-830B - Chinese zopangidwa chida, amene ntchito ndi anthu ambiri. Amene nthawi zonse amachita zinthu zamagetsi, simungakhoze kuchita popanda zida zimenezi. Nkhaniyi imafotokoza zimene Multimeter Deuteronomo-830B. Malangizo Lofotokoza chipangizo limalola ntchito ngakhale kwa oyamba.

Kupezeka ndi zitsanzo zambiri kuti amasiyana quality, molondola ndi magwiridwe.

chipangizo cholinga cha zotsatirazi miyeso izi:

• magetsi mfundo panopa;
• voteji pakati pa mfundo ziwiri mu dera magetsi;
• kukana.

Komanso Deuteronomo-830B Multimeter ndi zitsanzo zina zofanana angachichite ambiri ntchito zina:

• kuti mphete dera pamene impedance pansipa ohms 50 ndi alamu ndi;
• kudziyesa kukhulupirika kwa michenga yopangira zida zamagetsi diode ndi kudziwa voteji ake kutsogolo;
• onani michenga yopangira zida zamagetsi transistor;
• kuyeza ndi capacitance ndi inductance;
• kutentha kuyeza ndi thermocouple ndi;
• kudziwa amgwirizano chizindikiro pafupipafupi.

Kodi multimeter?

1. Imbani mapulogalamu anayeza makhalidwe mawonekedwe a manambala pa pulasitiki kapena galasi kudzionetsera.
2. Siwichi imapereka kusintha ntchito chipangizo, komanso ranges lophimba. iwo anayamba "Off" m'chigawo ulesi.
3. Zisa (cholumikizira) kwa unsembe mu atsogolera nyumba. Chinthu chachikulu ndi mawu Com ndi polarity zoipa, ndi zofunikira. Iwo anaikapo mu kafukufuku ndi wakuda waya. Kenako, amalembedwa VΩmA, ali polarity zabwino ndi wofiira kafukufuku.
4. Mayeso kusintha waya ofiira ndi wakuda ndi nkhupakupa.
5. The gululi kwa transistors kulamulira.

Multimeter Deuteronomo-830B: wosuta Buku ndi kufotokoza mwatsatanetsatane za modes kayesedwe

Osati aliyense amadziwa kuyeza magawo kofunika chipangizo. Pamene ntchito Deuteronomo-830B mita, malangizo opaleshoni ayenera kutsata chimodzimodzi. Apo ayi, zida mwina kuwotcha kunja.

1. Muyeso wa kukaniza

Ntchito n'kofunika pamene mukufuna kugwira Kulumikizana mu nyumba kapena kupeza yopuma maukonde kunyumba. Osati aliyense amadziwa, mu nkhani iyi, ntchito multimeter, ndipo iwe basi ndi kukhazikitsa lophimba kuti gawo kukana muyeso pa yoyenera muyeso osiyanasiyana. chipangizo ali ndi phokoso kusonyeza kuti dera chatsekedwa. Ngati chizindikiro palibe, izi zikutanthauza kuti penapake pali kusiyana kapena kukana mtengo dera apamwamba 50 ohms.

Osiyanasiyana kulimbikira osachepera (200 ohms) ndi yochepa circuited. Ngati interconnect mayeso ofiira ndi wakuda, chida liyenera kusonyeza mtengo pafupi ziro.

Multimeter Deuteronomo-830B Chinese kupanga ali zotsatirazi mbali pamene kuyeza magetsi kukana:

1. A mkulu kuwerenga molondola.
2. Pamene kuyeza impedances yaing'ono kuchokera ku kuwerenga ayenera subtracted mtengo analandira pa probes kukhudzana. Kuti tichite zimenezi m'mbuyomo kutsekedwa. Pa ranges zina zolakwa gawo yafupika.

2. Kodi kuyeza DC voteji

The chipangizo masiwichi kwa gawo DCV lagawidwa 5 magulu. lophimba ndi kugwira osiyanasiyana mwadala akuluakulu mfundo. Pamene kuyeza voteji amaperekedwa kwa batire 3 kapena 12 akhoza kuika udindo gawo "20". sayenera kuyikidwa pa mtengo waukulu, monga kuonjezera kuwerenga kusokera ndiponso mwina kuwotcha pa unit m'munsi. Pakuti miyezo akhakula, ngati mukufuna molondola 1 yekha, mita akhoza mwachindunji anaika mu malo a "500". Mofananamo, sakudziwa pamene anayeza voteji udzakwaniritsidwa. Mukhoza Kenako kusinthana zosiyanasiyana ndi mfundo m'munsi. Pa pamwamba muyeso chizindikiro chenjezo "HV" imene imaunika mu chapamwamba kumanzere ngodya. voltages Large womuuza mosamala ntchito ndi chida, koma voltmeter ndi Multimeter Deuteronomo-830B ndi odalirika kwambiri kuposa ammeter kapena ohmmeter.

Compliance probes polarity optionally digito chipangizo. Ngati sakugwirizana, pa umboni wa mtengo sati kukhudzidwa, ndipo anasiya yotchinga umaunikira chizindikiro "-".

3. Kodi kuyeza AC voteji

Unsembe mu gawo ACV ndi chimodzimodzi mu DCV. Mkulu voteji 220-380 B zingachititse kulephera kwa chipangizo chifukwa kugwirizana ndi lolakwika.

4. Muyeso wa DC

mafunde Small madera pakompyuta ndi amayezedwa gawo DCA. Mu kusinthana maudindo zosavomerezeka voteji kayesedwe. Pankhaniyi, dera lalifupi amapezeka.

Kuyeza mtengo panopa 10 akutumikira monga mpando wachitatu, zomwe zimafunika kusunthidwa mu kafukufuku wofiira. Zikuonetsa akhoza kuchotsedwa masekondi ochepa. Childs ndi ammeter anayeza magetsi panopa. Ntchito chipangizo mu nkhani iyi, chisamaliro ayenera kumwedwa ndi pamene miyezo zofunika.

5. Control wa diodes

Motsogozedwa n'zosiyana chipangizo diode ayenera kusonyeza osawerengeka (unit kumanzere). Mu voteji patsogolo kudutsa ziwirizi ndi 400-700 MV.

Mu gawo lino mukhoza fufuzani Kutukula wa transistor lapansi. Ngati ankayimiridwa ngati awiri zosiyana m'gulu diode, m'pofunika kufufuza chilichonse kusintha pa wovulala. Kuti tichite zimenezi, zimaonekeratu kumene m'munsi. Pakuti mtundu pnp ayenera kuphatikiza-kafukufuku kupeza maganizo amenewo (m'munsi) kuti kafukufuku anasonyeza osawerengeka zoipa kwa ena awiri (emitter ndi wokhometsa). Ngati transistor ndi a mtundu npn, m'munsi ndi opanda kafukufuku. Kupeza emitter, m'pofunika kuyeza kulimbikira kusintha ake, amene nthawi zonse kuposa wokhometsa a. Kuti mchitidwe ntchito ayenera kukhala mu uthunthu wa 500-1200 ohms.

Prozvoniv kusintha multimeter mu kutsogolo ndi mayendedwe mobwerera, n'zotheka kudziwa zosalongosoka transistor kapena ayi.

6. hFE ca mabungwe odziimira

The chida tingadziwire panopa amveke chinthu h21-transistor. Ndi zokwanira iyo 3 zikhomo za zitsulo yoyenera Jack. Mtengo anasonyeza limapezeka nthawi yomweyo "h21". Kupeza zotsatira zolondola m'pofunika kusiyanitsa mitundu ya pnp (kumanja mapanelo) ndi npn (kumanzere mbali).

7. mwayi kukonza chipangizo

Pa Multimeter Deuteronomo-830B Malangizo kupereka nambala inayake ntchito. The zitsanzo amasiyana mzake pang'ono, ndipo ngati n'koyenera, aliyense angathe bwino, monga kuwonjezera capacitance muyeso, kutentha ndi zina zonse ntchito zina tatchulazi.

Kufotokozera Multimeter Deuteronomo-830B mu malonda ndi ndemanga kwathunthu zabodza.

Maziko a multimeter ali analogi ndi digito Converter (ADC).

Multimeter Deuteronomo-830B: dera ndi kukonza

Pakuti mtengo wotsika kunyamula chida zambiri ntchito Chip ICL7106.

Mu muyeso wa chizindikiro voteji wotumidwa kuchokera lophimba kudzera resistor R17 kuti athandizira 31 Chip lapansi. Pamene alternating voteji chimaonekera, kumachitika mwa rectification diode D1, inatuluka ndi unyolo mbendera komanso amapita ku mapeto 32 tchipisi.

Anayeza DC panopa amalenga voteji dontho kudutsa resistors, ndiyeno chizindikiro nazonso kudyetsedwa kwa athandizira chitetezo dera 32. The lama fuyusi unapangidwa 0.2 Zogwiritsira athandizira.

chipangizo kawirikawiri amalephera imfa ya kulankhula ndi ngati si bwino anatembenukira. Choyamba, onani ndi kusintha lama fuyusi.

chipangizo ntchito molondola ku muyeso wa voteji, komanso kutetezedwa overloads pa athandizira. Kulephera kumachitika pa kukana kapena muyeso panopa.

Anatentha resistors zingadziŵike zowoneka, ndi diodes ndi transistors kokayezetsa ntchito njira anapatsidwa pamwamba. Macheke pa kupitiriza komanso lodalirika kulankhula ndi.

Pamene akukonza chipangizo chamagetsi woyamba limafufuza magetsi. Ndiye kukonza Chip ndi kufufuzidwa. Ziyenera kukhala chopindulitsa, ngati voteji pa osachiritsika 30 3 V, ndi pakati pa osachiritsika mphamvu ndi Chip wamba ayi kusokonezeka.

Pamene kuziphwasula n'kuyamba sayenera kutaya mikanda, popanda zomwe izo sizikanakhala odalirika fixation.

Pamene kusintha batiri?

Mphamvu kotunga zimasiyanasiyana milandu mofulumira a manambala mu kuwonetsera ndi kupatuka zotsatira muyeso ku makhalidwe amadziwika kuti idzatha. Battery chithunzi chimaoneka pa TV. Kuti m'malo muyenera kuchotsa chikuto, kuchotsa wakale ndi kukhazikitsa katunduyo latsopano.

Gwiritsani ntchito multimeter Deuteronomo-830B ndi batire yabwino kwambiri kusintha mosavuta komanso yosowa kwambiri. ochepa okha naye ntchito kwambiri. chipangizo n'zosavuta kuwotcha ngati ntchito molakwa.

Reviews chipangizo

Pa chipangizo monga ndi digito multimeter Deuteronomo-830B, makamaka ndemanga yothandiza. Iye ndi wodzichepetsa, zogwira ntchito zosiyanasiyana, ndi batire kumatenga zaka zambiri. Akonza mtengo onse otsika chipangizo. Comments kuoneka yekha opanda pake.

Probes ayenera m'malo, monga iwo mosavuta kuonongeka. Fundo iwo ndi pafupi muyezo ndi 0.5 ohms.

Pomaliza

Multimeter Deuteronomo-830B ndi chipangizo konsekonse, koyenera kuti DIY ndi akatswiri. Zikuyenera ntchito zambiri zofunika ndi mtengo. Bwinobwino ntchito zofunika kuphunzira mwatsatanetsatane zimene Multimeter Deuteronomo-830B. The malangizo zikugwira ntchito ayenera mosamalitsa anaona kuti asalakwitse chilichonse kuti zingachititse kuti kulephera kwa chipangizo.
